Abstract: A busway tap off system is provided for connecting an electrical supply to a distribution device. The busway tap off system comprises a joint mounted tap box configured for making an electrical connection between an electrical busway and a power distribution system including a downstream panel. The joint mounted tap box is a dynamically mounted electrical equipment and the downstream panel is a rigidly mounted electrical equipment. The busway tap off system further comprises electrical cables that connect the two equipments. The busway tap off system further comprises a nipple accessory that provides a flexible mechanical and electrical connection between the dynamically mounted electrical equipment and the rigidly mounted electrical equipment. The nipple accessory is configured as a rigidly-constructed flexible fitting that includes two axial slides that enable the nipple accessory to move with the dynamically mounted electrical equipment yet remains fixed to the rigidly mounted electrical equipment.

Abstract: A multi-bolt joint stack for use in an electrical power distribution system. The joint stack includes (1) a plurality of conductive plate sets, each plate set including a first conductive plate and a second conductive plate separated by a first spacer and a second spacer; (2) a first clamping bolt extending through the plurality of conductive plate sets and the first spacer of each conductive plate set; and (3) a second clamping bolt extending through the plurality of conductive plate sets and the second spacer of each conductive plate set. The first and second clamping bolts are separated from each other to define a plurality of pockets within the joint stack, each pocket being formed by the first and second conductive plates and first and second spacers of the plurality of conductive plate sets. The pockets are configured to receive electrical stabs. Numerous other aspects are provided.

Abstract: A system is provided for a power distribution enclosure that includes an electronic circuit component. The system includes a conductive adapter having a head, and a circuit breaker base adapted for mounting to the power distribution enclosure. The circuit breaker base has an aperture adapted to receive the head of the conductive adapter. The head of the conductive adapter has a shape that substantially prevents rotation of the conductive adapter when the conductive adapter is inserted into the aperture. The conductive adapter is configured to draw away or absorb heat from the electronic circuit component and move the absorbed heat out of the power distribution enclosure. The circuit breaker base is adapted to substantially prevent heat from escaping from the conductive adapter into the power distribution enclosure. Numerous other aspects are provided.
